摘　　要：提出了一种基于光学鼠标传感器的转速测量方法。分析了转速测量原理,解决了光学鼠标传感器ADNS-3080的软件初始化和镜头对焦等关键问题,设计了基于光学鼠标传感器的转速测量试验系统。试验结果表明:这种方法能准确判别转向,对于本试验系统,在1000 r/min范围内具有良好的线性度和快速响应性。该方法适用于低速转动部件的转速测量与转向判别。A novel rotation speed measurement method based on optical mouse sensor is proposed. The rotation t principle is analyzed. The key problems such as software initializing of the optical mouse sensor ADNS --3080 and focusing of the lens are solved. An experiment system based on optical mouse sensor is designed. The experimental results indicate that this method can exactly distinguish the direction, the linearity and responsivity of the experiment system are good in the 1 000 r/min scope. The method is suitable in the low-speed survey and direction distinguishing.
